NOTES:
1. Signal levels are referenced to common.
2. * Indicates that the stated voltage threshold depends upon the value of the - 7 V (nominal) supply. For example, if the value
of the - 7 V supply is actually - 7.1 V (0.1 V lower than - 7 V), then the LOW value given for pin 25 would read < - 6.8 V
(which is 0.1 V lower than - 6.7 V).
3. ** See OV DRIVE (pin 6) description in paragraph 4-30.
4. *** Minus one diode drop.
5. (↑) Indicates that hysteresis is involved in the trip voltage level and a transition from a lower voltage up to the indicated level
must have occurred (e.g., THERM, pin 14, is HIGH only when the voltage increases to a level >2.8 V ±0.3 V).
6. (↓) Indicates that hysteresis is involved in the trip voltage level and a transition from a higher voltage down to the indicated
level must have occurred (e.g., THERM, pin 14, is LOW only when the voltage decreases to a level <2.5 V ± 0.15 V).
